Dongfeng Science and Technology Minister Hou Yuming talked about the transformation of China's automotive technology research results from the State III EGR

At present, the application technology of China's automotive electronics technology is already high, but few are mastered in the core areas of electronic control. Really grasping high value-added high technologies requires the joint efforts of our automotive companies and research institutes.

Some of the things that we went to talk about half a year ago are somewhat out of date. However, to explore the deep-seated contradictions behind the cases, it is worth thinking about at any time.

In June 2008, when the country was about to implement the National III emission regulations, China National Heavy Duty Truck launched the H-Pump + EGR Engine III heavy-duty truck product, which was much lower than the price of the EFI technology's State III engine heavy-duty trucks. Flavoured, but it also triggered a large-scale discussion within the industry. In addition to the significant engine risks associated with EGR technology, the controversy also includes whether EGR can meet the upgrade requirements for future National IV emissions as a countermeasure against China III.

"The key reason for the dispute is actually that it is cheap." According to Hou Yuming, head of the Dongfeng Science and Technology Department and auto expert (as shown on the left), in the price-sensitive heavy truck industry, this means that Sinotruk's EGR products Will occupy more market share. This is also true. In the heavy truck industry last year's trend of “high before and after low”, China Heavy Truck heavy trucks equipped with EGR engines stood out.

"But the technology of EGR itself is not very advanced. In the past, there were manufacturers abroad for R&D and production. In China, any truck company with a large scale can produce it. The problem is that before that, everyone did not think that it would be studied. In fact, no one dares to think this way, but EGR is indeed a headache, but this is exactly where China National Heavy Duty Trucks is highly skilled. This kind of thinking and spirit is worth admiring. Although this is not the result of hope, I also think about this issue. : Why not come out is neither an EFI nor an innovative route to EGR? Even high costs are possible.” Hou Yuming said bluntly.

The statement from China National Heavy Duty Truck also seems to prove this analysis.

China National Heavy Duty Truck production EGR is actually a last resort. The reason is simple: the fact that the electronically controlled common-rail system of the engine that meets the emission requirements of State III is monopolized by foreign companies has always been the detriment of the industry. Domestic engine companies have also complained about this. In desperation, it is influenced by the influence of the Chinese market and the idea of ​​contending with overseas monopolies. China National Heavy Duty Truck launched the EGR engine product and conducted a powerful crackdown on its monopolistic behavior. Although it is controversial and needs to pay a lot of money.

The data show that in the current domestic III diesel engine market, Bosch high-pressure common rail system with world-renowned is in an absolute monopoly position. Two years ago, the price of Bosch's high-pressure common rail system provided to China was set at more than 20,000 yuan each, and it also charged an expensive product calibration fee, which resulted in high profits.

China National Heavy Duty Truck's production of EGR seems to have received immediate results, and eventually led Bosch to drop its product prices. In September 2008, Bosch Common Rail System reduced the price of domestic engine companies. The rate of price reduction was as high as 10%. Although the price reduction was mainly directed at the common rail system of small engines, it was generally believed by the industry that this was a victory for Sinotruck to contend with. Although Bosch doesn't disagree with this, he believes that similar Bosch price cuts will occur several times a year, which is normal business behavior.

In addition, domestic companies have made some achievements in the research and development of the diesel engine EFI system in the past two years and have caused the monopoly giants to be scruples.
The products of the Wuxi Oil Pump Yoke Research Institute and the Liaoning Xinfeng Group Jier Fuel Injection Co., Ltd. have begun trial production and preparation; the Wang’s Witton’s electronically controlled combination pumps have begun to be loaded in small batches; FAW has also launched the first Independently developed high-pressure common-rail State III diesel engine. In addition, high voltage common rail products such as Denso and Delphi have also landed in China one after another. Among them, Denso's high pressure common rail system production plant was started and put into operation in Changzhou in 2007. In the face of increasingly fierce competition, the situation in which Bosch dominates the world may be broken.
